Autosomal dominant congenital cataract associated with a missense mutation in the human alpha crystallin gene CRYAA.
Congenital cataracts are a common major abnormality of the eye that frequently cause blindness in infants. At least a third of all cases are familial; autosomal dominant congenital cataract (ADCC) appears to be the most common familial form in the Western world. We have mapped an ADCC gene in family ADCC-2 to chromosome 21q22.3 near the alpha-crystallin gene CRYAA. By sequencing the coding regi...
متن کاملA recurrent missense mutation in GJA3 associated with autosomal dominant cataract linked to chromosome 13q
PURPOSE To map and identify the genetic defect underlying autosomal dominant cataract segregating in a 5-generation Caucasian American family. METHODS Genomic DNA was prepared from blood leukocytes, genotyping was performed using microsatellite markers, and logarithm of the odds (LOD) scores were calculated using the LINKAGE programs. Mutation profiling was performed using direct exon cycle-s...
متن کاملA missense mutation in the gammaD crystallin gene (CRYGD) associated with autosomal dominant "coral-like" cataract linked to chromosome 2q.
PURPOSE Hereditary cataract is a clinically and genetically heterogeneous lens disorder that usually presents as a sight-threatening trait in childhood. The purpose of this study was to map and identify the mutation underlying an autosomal dominant form of coral-shaped cataract segregating in a three generation Caucasian pedigree. METHODS Genomic DNA was prepared from blood leucocytes, genoty...
متن کاملA novel GJA8 mutation (p.I31T) causing autosomal dominant congenital cataract in a Chinese family
PURPOSE To identify the genetic defect associated with autosomal dominant congenital nuclear cataract in a Chinese family. METHODS Family history and clinical data were recorded. The genomic DNA was extracted from peripheral blood leukocytes. All the members were genotyped with microsatellite markers at loci considered to be associated with cataracts. Two-point logarithm of odds (LOD) scores ...
متن کاملA novel mutation in GJA3 (connexin46) for autosomal dominant congenital nuclear pulverulent cataract.
PURPOSE Autosomal dominant congenital cataract (ADCC) is a clinically and genetically heterogeneous lens disorder that usually presents as a sight-threatening trait in childhood. Here, we described a six-generation Chinese family presenting with morphologically homogeneous "nuclear pulverulent" cataracts. METHODS A whole genome scan was performed with polymorphic microsatellites in the Human ...
